Lohring, Thanks for the info I am not ready for CCA but I will buy if they become available to help bring the cost down. MikeDental "stainless steel" is actually a chrome cobalt alloy. It originally was brittle, but the alloys used today are more ductile and very tough. Castability is an important factor as well. Traditional lost wax casting is being replaced by laser sintering. Wax patterns are being 3D printed as well. Both processes would be great for one off props. You would need deeper pockets than the typical model boater. I was quoted $80 for a casting if I furnished the wax pattern. 3D printed patterns run around the same cost if multiple props are printed at once. They don't need to be the same design. Also you would need a .stl file of the design you want. That can be direct from a CAD design or from a scan of an existing prop.
